Nonis was feeling ill during the second period and was examined by team physicians at Air Canada Centre before being taken to a hospital.

"As a precaution, (Nonis) was asked to go to the hospital for further testing," the team announced in a press release Sunday. "He has progressed very well overnight and is expected to be discharged today."

Nonis, 47, is in his second season as the Maple Leafs' general manager.
